Definitions

  • An enclosed conduit 110 is formed in each vane 107 between the surfaces 108 and 109 of that vane.
  • the surface 108 of each vane faces the incoming gas stream and thus as the direction of gas flow is changed the mist or liquid droplets 111 present in the gas stream will, by inertial elfect, impinge on surface 108.
  • These liquid droplets 111 will, by the viscous force of the gas-liquid interface, tend to migrate along surface 108 or wet the surface and form a film that tends to migrate along the surface in a downstream direction.
  • a slot 112 is provided in each surface108 near the downstream extremity of the curved, i.e., gas flow turning, portion of the surface whereby the turning of the gas stream is virtually completed before the slot on 112 is encountered by the gas stream.
  • the droplets of liquid removed from the stream of gas and entering conduits 110 may contain suspended Qr. dissolve solids, such as salt, that will tend to adhere to the walls of conduits 110 or a particular liquid itself may tend to adhere to the walls of the conduits. Over a period of time the accumulation of adhering solids and liquids may tend to clog conduits 110, sump 115, duct 126 or passageway 114 thereby interfering with the heretofore described removal and draining of the droplets of liquid.
  • a wash-down assembly generallydesignated 130, may be provided with device 100 for introducing a liquid at the top of each conduit 110 to wash out the conduits.
  • a device for separating liquid droplets from a stream of flowing gas comprising a housing having an inlet and an outlet angularly positioned relative to each other for the gas stream to enter the housing in one direction and to leave the housing in a direction at an angle to the direction of the entering gas stream, a plurality of vanes mounted in said housing having curved surfaces for causing the gas stream to change said direction of flow from said inlet to said outlet, one said surface of each vane confronting the entering gas stream for droplets to impinge on that said one surface and having a downstream portion relative to the direction of gas flow, conduit means provided with each said vane, and a slot means extending transversely of each said vane and communicating said conduit means with the downstream portion of said one surface of that vane for the droplets on said one surface to migrate through said slot means into said conduit means whereby the droplets are removed from the influence of the flowing gas stream, and fluid suction means connected to said conduit means for continually drawing off the droplets and gas from said conduit means.
  • a device for separating liquid droplets from a stream of flowing gas comprising a housing having an inlet and an outlet angularly positioned relative to each other for the gas stream to enter the housing in one direction and to leave the housing in a direction at an angle to the direction of the entering gas stream, a plurality of vanes mounted in said housing having curved surfaces for caus ing the gas stream to change said direction of flow from said inlet to said outlet, the said surfaces of each said vane curved and shaped to form a thickened cross section for efliciently changing the gas flow direction, one said surface of each vane confronting the entering gas stream for droplets to impinge on that one surface and having a downstream portion relative to the direction of gas flow, conduit means provided with each vane and having a slot means extending transversely of said vane for com municating with the downstream portion of said one surface of that vane for receiving droplets migrating along said one surface, means for supplying fluid to the inside 8 of each said conduit means for washing down the inside of said conduit means,
